In this week’s bumper Christmas Compendium of Questions: what’s the worst tonguetwister in the world? What’s wrong with Daniel Radcliffe? When is it rude to call someone fat? Does an apple a day keep the doctor away? What is a rock polishing kit? Was W K Kellogg a bit odd? What is a blue riband? Who in the bible is still alive? And finally, what is a henge? Listen in to hear Fevzi and Nick fail to answer all of these questions adequately. Tell us what you think at: tro@gadgetdetective.com.
